If you look on your laptop keyboard, there is probably a - (minus) sign on the :/; key. You need to hit function to use it. I think, but am not positive, that this is the key you use as well for taking screenshots.

In game, click on the options button. Then click on the tab for keyboard functions. In that list, the "screenshot" has a key or 2 you can affix to it. Set it to whatever you desire. Usually it is the "-" key. After taking a few pics, follow what rascricket said. I hope that helps.

Your number pad is still there. It just shares other keys now. Look at the J, K, and L keys. You should see the numbers 1, 2, and 3 printed on them in a different color. To use the numbers instead of letters, press the "Fn" key with it. For a screenshot, you'd press the "Fn" and ";" keys together.

Screenshots are stored in C:/Program Files/Sony/EverQuest/Screenshots.
